1.2.1 Editing PLC-programs
In the operating mode PLC EDITING MODE (TNC 406 Soft key EDIT) an instruction list can be edited
via TNC keyboard.
The keys of the TNC 306 assume new assignments, which are indicated on a special tactile
membrane that is place over the TNC keyboard. The tactile membrane is included with this
Technical Manual. Before editing a new program, it is necessary to reserve memory in the
UTILIZATION/ MEMORY mode.
After the ENT key is pressed, the editor identifies itself with
"0 EM"
"0" stands for program line 0 and "EM" for End of Module.
When entering an instruction, "EM" automatically moves downward by one line.
The PLC editing mode can be exited by pressing the END key/ soft key.
